Safety and operating instructions
General terms
System introduction
Warning:
During assembly, testing, and operation, the demonstration
board poses several inherent hazards, including bare wires,
moving or rotating parts, and hot surfaces. There is a danger
of serious personal injury and damage to property, if the kit
or components are improperly used or installed incorrectly.
The kit is not electrically isolated from the AC/DC input. The
demonstration board is directly linked to the mains voltage.
No insulation has been placed between the accessible parts
and the high-voltage. All measurement equipment must be
isolated from the mains before powering the board. When
using an oscilloscope with the demonstration board, it must
be isolated from the AC line. This prevents a shock from
occurring as a result of touching any single point in the
circuit, but does NOT prevent shocks when touching two or
more points in the circuit. Do not touch the demonstration
board after disconnection from the voltage supply, as several
parts and power terminals, which contain energized
capacitors, need to be allowed to discharge.
2.3.2
2.3.3
All operations involving transportation, installation and use, as well as maintenance, are to
be carried out by skilled technical personnel (national accident prevention rules must be
observed). For the purpose of these basic safety instructions, “skilled technical personnel”
are suitably qualified people who are familiar with the installation, use and maintenance of
powered electronic systems.
Demonstration board intended use
The STEVAL-IHM023V2 demonstration board is a component designed for demonstration
purposes only and is not to be used for electrical installation or machinery. The technical
data as well as information concerning the power supply conditions should be taken from
the documentation and strictly observed.
Demonstration board installation
The installation and cooling of the demonstration kit boards must be in accordance with the
specifications and the targeted application.
● The motor drive converters are protected against excessive strain. In particular, no
components are to be bent or isolating distances altered during the course of
transportation or handling.
● No contact must be made with other electronic components and contacts.
● The boards contain electro-statically sensitive components that are prone to damage
through improper use. Electrical components must not be mechanically damaged or
destroyed.
